Press Release Summary:
Mixed signal system-on-a-chip (SoC), M3000, combines building blocks necessary to control and position multi-phase step motors while also working as high-speed, general-purpose MCU with communication, analog, and system functions. Along with phase current control circuits, SoC features acceleration, velocity, and position control circuits that free up CPU to perform other system control functions. CPU block has 20 GPIO lines and RISC-based Atmel AVR core running at 20 MHz.
Original Press Release:
M3000 Motion Controller System-on-a-Chip
The M3000 Motion Controller, from System Semiconductor Inc. in affiliation with Intelligent Motion Systems, is a highly integrated, mixed signal system-on-a-chip combining the major building blocks necessary to control and position multi-phase step motors while also working as a high-speed general purpose microcontroller incorporating extensive communication, analog and system functions. The M3000 is offered in 160-pin quad package (LQFP), 128-pin quad package (TQFP), and 128-ball grid array (TFBGA).
Integration of the M3000's patented phase current control circuits enables motor performance to reach new limits of increased speed and smoothness while lowering audible noise and vibration. And with advanced acceleration, velocity and position control circuits virtually eliminating corresponding time critical tasks, the CPU is freed to perform other system control functions allowing system throughput rivaling high-end DSP's costing more.
Incorporation of the M3000's extensive communication and general analog functions provides the user the capability to control a large variety of systems without additional circuits. By integrating all major system's functions into one system-on-a-chip, performance and reliability are greatly enhanced while cost and time to market are reduced. A large temperature range makes the M3000 ideal for commercial and industrial applications.
Price: $13.50 each / 1000 piece quantity
